I can tell you that the MP780 does not know the difference between a BCI3 and a BCI6 cartridge so there is definitely another issue.

Try to reset to factory .
Remove ink cartridges and print head.
Power off machine and unplug for 10-15 minutes.
Restart machine and install head and cartridges.

Cleaning won't help this one, you need a new printhead,QY6-0034-010. It only says wrong cartridge when the printhead is burned out.

It's worth repairing, That error on a Canon is saying that the printhead is bad, not your cartridges. The part number for your printhead is stamped on the side of the printhead could be QY6-0049-000 but I'm not sure.

try changing the ink cartridges.
This may have happened due to low ink levels. Also try reinstalling the printer driver.
If the print cartridges are damaged this problem will pop up. Even static electricity in human hand could damage the print cartridges.
